Hitachi Energy–LKAB–Scania pantograph trucks: design and power notes for mine planners

30 Second Briefing
Hitachi Energy, LKAB and Scania are developing an autonomous downward pantograph charging system for battery-electric haul trucks at LKAB’s Malmberget iron ore mine in northern Sweden. The solution will integrate Scania’s electric heavy-duty mining trucks with Hitachi Energy’s high-power charging infrastructure to allow automatic connection to overhead conductors without driver intervention. For mine planners and electrical engineers, this points to trolley-like, on-route charging concepts that could cut diesel use on ramp hauls and shift significant load onto grid-supplied power.
Technical Brief
- Downward-facing pantograph mechanically reaches up to fixed overhead conductors, avoiding truck-mounted masts or booms.
- Autonomous connection logic is intended to synchronise truck positioning, contact pressure and current ramp-up without operator input.
- Integration work includes coordinating vehicle control software with substation and line-side protection, relays and interlocks.
- Electrical engineers will need to address arcing, ice/snow contamination and mechanical wear at the pantograph–wire interface.
- For other hard‑rock mines, similar on‑route systems could be staged first on fixed-gradient main ramps.
Our Take
Hitachi Energy’s work with LKAB at Malmberget sits alongside its MoU with Volvo Construction Equipment on end‑to‑end electrified quarrying sites, suggesting the company is building a modular toolkit for high‑power mobile equipment rather than one‑off mine solutions.
Across our mining and infrastructure coverage, Hitachi Energy repeatedly appears in HVDC and ‘grid‑to‑process’ projects, so integrating a downward pantograph at LKAB’s Malmberget mine is likely to be engineered as part of a broader high‑voltage, grid‑connected architecture rather than a standalone charging add‑on.
Malmberget is one of the few specific regions that recurs in our sustainability‑tagged mining items, and pairing it with Scania and Hitachi Energy here signals that northern Scandinavian iron ore operations are becoming a proving ground for heavy‑haul electrification concepts that can later be exported to other high‑latitude, grid‑rich mining belts.
